Accupro 12182544 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO 12182544 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/8 inch diameter with a 0.0450 inch corner radius and a 7/8 inch length of cut, making it well suited for profiling, contouring, and slot milling where a controlled edge radius is required. The TiCN coating increases surface hardness and reduces friction, extending tool life in ferrous and non-ferrous materials. With 4 flutes and a 40-degree helix angle, it provides efficient chip evacuation and a smooth finish. This is a single-end, centercutting tool ground from micrograin carbide for tight dimensional tolerances.

This end mill is used in CNC machining centers and manual mills across general metalworking, tool and die, mold making, and production machining environments. It is suited for cutting steel, stainless steel, cast iron, and similar materials where TiCN coating offers a performance advantage. The right-hand cutting direction and right-hand flute spiral are standard for conventional CNC setups. Machinists and tool room technicians are the primary installers and operators of this tooling.

Key Features

• 0.0450 inch corner radius reduces stress concentration and extends part life at machined edges
• TiCN coating improves wear resistance and tool longevity in ferrous and non-ferrous cutting
• Micrograin solid carbide substrate provides rigidity and dimensional stability
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design allows plunge entry directly into the workpiece
• Single-end configuration with a 3/8 inch shank diameter for standard collet and end mill holder compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for 3/8 inch collet chucks, shrink-fit holders, and end mill holders accepting a 3/8 inch shank diameter in standard CNC and manual milling machines.

Installation Notes

This tooling is installed and operated by qualified machinists and CNC operators. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Secure the shank fully within the holder to the recommended engagement depth and torque the clamping mechanism per the holder manufacturer specifications. Inspect the cutting edges and coating for damage before each use and do not exceed the tool's rated cutting parameters for the material being machined.
